1 Executive Summary

This report analyzes global disparities in DTP (Diphtheria, Tetanus, and Pertussis) vaccination coverage using UNICEF data. It explores vaccination trends, top-performing countries, and the influence of national income (GNI per capita) on healthcare outcomes.

Key findings reveal:

  • Significant regional inequalities in vaccine access.
  • A positive correlation between higher income and better immunization rates.
  • The need for targeted healthcare interventions in low-coverage regions.

The analysis supports strategic actions aligned with SDG 3 (Good Health and Well-Being) to ensure equitable vaccine distribution globally.

2 Introduction

Vaccination remains one of the most effective public health strategies to safeguard child health. Among vaccines, DTP coverage is widely recognized as a key indicator of healthcare system strength and equity.

This report examines global DTP vaccination rates by analyzing UNICEF’s latest child health dataset. It also explores the relationship between economic prosperity and immunization coverage to identify patterns, disparities, and opportunities for improvement.

3 Data Setup

4 Methodology

We extracted and analyzed DTP vaccination coverage indicators, complemented by economic metrics (GNI per capita), to uncover patterns and disparities across countries and over time.

5 DTP Vaccination Data Preparation

6 Analysis and Visualizations

6.1 Global Distribution of DTP Vaccination Coverage

Insight:
Coverage varies greatly, with Sub-Saharan Africa and parts of South Asia showing lower immunization rates.

6.3 Top 10 Countries with Highest DTP Coverage

Insight:
Top-performing countries achieve immunization rates near 100%, highlighting effective healthcare programs.

6.4 GNI per Capita vs DTP Vaccination Coverage

Insight:
Higher income tends to correspond with better vaccination coverage, but governance also plays a key role.

7 Conclusion

This study highlights global disparities in DTP vaccination coverage, linked closely to national income levels and healthcare system strength. Public health interventions and equitable healthcare investments remain critical to achieving SDG 3 goals globally.
